Geometry Calculator

1. Calculate the Area of a Circle

2. Calculate the Area of a Rectangle

3. Calculate the Area of a Triangle

4. Quit

Enter your choice (1-4): If the user enters 1, the program should ask for the radius of the circle and then display its area. Use the following formula:
area p r

2. Use 3.14159 for p and the radius of the circle for r . If the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle's area. Use the following formula:
area = length * width

If the user enters 3 the program should ask for the length of the triangle's base and its height, and then display its area. Use the following formula:

area = base * height * .5

If the user enters 4, the program should end.
